Ok so I just have a quick qustion and I have searched but can't find an answer. I think my 4g radio may be broken because when I try and turn it on it sits for a minute then says unknown and turns back off. The coverage map shows me having 4g in my area but it could be wrong. It seems to me that I should be able to turn on the 4g radio and it will be on and regardless of signal and will keep searching for a signal but I've never actually had a working 4g connection so I don't know if this is regular behavior or if my 4g is defective and I need to get a replacement.

Just wanted to update incase anyone else has this problem. I tried flashing back to complete stock di18 but still no 4g so I took it in to sprint where they just did a data reset and then sat there scratching there heads when it still didn't work, they were absolutely no help and at the end they pretty much told me I could buy a new phone or live with it. So took it back to radio shack where I bought the phone and the replaced it no problem. Now my 4g radio works great and I even have coverage in my erea B-)
Thank you for your advise

Hey everyone,
I just bought a refurbished Nexus S for $200. I thought it was a pretty good deal. Loving the phone so far. However, last night I lost data services. The signal bars which is normally green was "greyed" out. I tried the web browser, twitter and nothing was working. Eventually I got data back in about 30 mins or so. I didn't think anything of it. Well, it happened again today. Signal bars were greyed out again. I have less than 14 days to return/exchange my device. Should I exchange it? Is this a known issue with the Nexus S? Just an FYI, I have 2 lines and data is working fine on my BlackBerry.
I'm running stock OS, 2.3.6
Any help is greatly appreciated.
Thanks
Hate to break it to you but one of the few bad things about this phone is its reception. Check what radio version. Your on. If it doesn't say ke1, go on peter alfonsos web site and download the ke1 radio and flash it through cwm. See if that helps.

I'm assuming that requires me to root the phone? So if I choose not to root my phone I'm going to have this ongoing issue?
rooting and installing this radio won't necessarily help. I have the I9020A with the newest radio and i do have this problem sometimes - I'm losing signal and it recovers in random time. the weirdest thing is that I can find my network when I'm searching manually for networks. You are on rogers (based on your avatar), so i can only guess we have the same model. My brother has the I9020A also, and he has similar yet different problem - when he lost signal due to no reception areas, he has to go into airplane mode and back to normal to recover the signal. he also has the newest radio (UCKF).
You should also notice that rooting your phone will make you lose your warranty, and i guess that also the the right to exchange it.
Yes the model I have is the same as your brother's. I know in general Samsung has bad radios. Is it because it's made by Samsung or is it particular to the Nexus S? I have been reading the same issues with the Galaxy Nexus, so I'm guessing it's Samsung.
I don't plan on rooting it because I know it will void the warranty and I won't be able to return/exchange it.
i have same case , which is , when i am back in my room ,away from streets and lots walls for signal to go through , 3G signal is **** , however, you can switch it to 2G signal in order to no to miss any phone calls and SMSs. but , you Internet speed will greatly reduced ... like max 8 kb/s

You should see if your phone is set to wcdma/gsm mode. My room is a inner room also and when it loses 3g signal, it jumps automatically to gsm mode (internet speed is not an issue, WI-FI FTW ).

Well I do have an ns4g and since these forums aren't seperated by model its easy to see why I would make the wrong recommendation. What are you following me around? Instead of being a troll why don't you post something useful and try and help the op bud.

What Radio do you currently have?
I usually had this problem and I had to go into mobile network settings, uncheck 'Data Enabled' and select 'Network Operators' until it found my carrier.
Have you tried checking the Airplane mode and disabling again?
If you dial *#*#4636#*#* when this happens and you go into phone information, do you see it connected?
Ever since I flashed the latest (un)official 4.0.4 deodexed/rooted leak along with the new radio I've been having a hard time keeping a data coverage. It keeps switching to 1x Edge coverage or losing signal period. Its particularly obvious in areas(like at work) where I usually have 4 bars of 3g. The only fix I've found is to switch to airplane mode and then back, or to reboot the phone. Is anyone else having problems like this with either the official OTA or the (un)official rooted leak?

Sprint issues maybe?

I had issues earlier when I first flashed the radio.
I tried doing a profile/prl reset/update and everything seems back to normal now.
I tried prl and profile and it worked for an hour or so... Its been like that since the day the rom was leaked. An hour ago I wiped my cache and dalvik cache and flashed the new air kernel and so far so good Maybe I just had something goofy in my cache? I'll check back tomorrow, maybe it was just operator error somewhere along the way

I had the exact same issues
What helped me? Fastboot flashing previous radio. I guess it's coverage in my area? But I took the leaked ROM plus radio and flashed all the img's through fastboot and after a day or so I would get stuck in 1x. Like you, I usually got 3G.
I'm on the previous radio now and the problem went away

On thursday and friday i had no data at my desk at work, today i'm fine. I didn't change anything, didn't even wipe cache. Pretty sure it's sprint.
Also, if I left my desk and walked two streets over, it worked great.
Before 4.0.4 I think there was a hack on stock GB roms that the phone wouldn't show when it entered 1x. It was pretty obvious with the slowdown, but the indicator never showed it. With 4.0.4 I believe that hack is now gone and it really does show 1x vs 3G in the situations it's happening in.
This is happening to me. I have tried all of the radios. My wife's evo 3d has full 3g right next to my phone.
I have full wiped reflashed and tried all the radios.
Nothing seems to work.

i got a older EVO jus to check
and because curiosity was killin me
the HTC has a good radio
both my ns4g's
leave a lot to be desired
fwiw
Anybody get this fixed? I'm still in and out of 1x.

If you know your MSL, you might try dialing *#*#72786#*#* for a fresh activation. It's helped me in the past after flashing radios.
Tried everything. Finally took the phone to sprint. They said it there was a problem. Paid $35 for a replacement.

Hello, i am unable to get 4g on my g2. It is international version. Any ideas on how to solve this? I have alresdy called my telco and requested forb4g to be on. Unfortunately still no 4g after 2 days..
Same problem with my d802.
No clues how to fix it..

My friend recently had an issue with his 4g cutting out. Airplane mode being toggled on and off seem to bring it back, but only for a short amount of time. Finally found a thread on VZW forum of people having the same issue. I'll link to it when I find it again...
Come to find out it was the sim card. Got a replacement and had solid 4g with no cut outs. Unfortunately my friends G2 screen died the next day so he couldn't reap the benefits lol

Hey guys- I'm having this same issue, on my D801 with CM10.2 and DarkPA (tried both). Started yesterday evening - my phone automatically switches back to GSM/WCDMA preferred no matter what I pick. It's only picking up 3G/H+. I'm in the Chicago area.
I called TMobile and they gave me some BS about it being my tower, but also software issue, etc etc. The guy was just saying things. Still no luck. I am going to go to the TMo store today to see if a new SIM card will fix it.
EDIT: Turns out the cell tower near me is just being strange. I can walk down the street and get LTE, but when I walk towards my apartment the LTE dies and switches to 3G/H+. Weird.
Hi, thanks for replies. I got my 4G overtime. Happened to my brother as well. He waited 2 weeks before getting 4G. And btw, is H H+?

Basically I have tried stock reset using LG Flashing tool i have rooted and tried numerous roms, but the problem is i boot my phone it has 4gLTE full then 5 minutes in it switches to 3g network. I have called verizon and tried everything they told me. Also i have even tried and made sure it was on the correct network which is Global or CDMA/LTE
I wanted to know if any deveopler can help me here to figure out the issue with why its not staying connected to 4g?
One of two things. There is issues with the towers around u which would be a Verizon problem. Or its hardware related

its sounding like its hardware related before i upgraded to the LG g2 i had .. i even dialed *228 to locate towers my area is all red on 4glte and im right next to the tower
can someone please help me with this issue it is irritating me very much because i pay for 4glte not 3g ****
so no update on this no one having the same issues as me loosing 4glte and connecting to 3g
Have you tried a new SIM card? On some LTE devices dialing *228 can actually screw up the SIM data. You should try a new card.

Have you tried any of the different radios / modems? Might be worth a shot.

Just got my G2 a couple days ago and I can confirm that I am having the same issue. I haven't found any fixes yet. It does seem that as long as I am actively using the data network, I keep 4g. Once I quit using data or go to wi-fi though, I switch back to 3g after a short period. Quick toggle of airplane mode and almost instantly connects back to 4g again, with the same results of dropping shortly thereafter.
I'm in a spotty area, 4G sticks on one bar and rarely reverts to 3G. Signal loss very rarely. Always comes back auto. Faulty modem sw, SIM, hardware, or towers.
I called lg about the issue they say it was Verizon's fault and there radios .. So they sent me the international version works perfect now I would recommend anyone here to drop Verizon they are **** and highly overpriced
Ever since I took OTA update I cannot get the LTE to stay locked on it keeps going back to 3g. My wife has the same phone and hers stays in LTE. So I know it isn't the towers. She took the OTA update also. The only difference is mine is rooted on the new KK. Anyone else have that problem? Sorry I'm on Verizon Network VS980 4gG LTE
Well I downgraded back to Jelly Bean VS98012B and stayed stock without root and still have the same problem with LTE. I switched Airplane mode off and then back on and I get LTE with 2 bars then it goes back to 3g with 2 bars. I wonder if its the phone or if I am being throttled by Verizon?
Well I seem to be answering my own questions. Turns out my sim card is bad. I tried my wife's and the phone went to LTE and stayed. I put mine in her phone and it stayed 3g. So hope this helps anyone else that would experience this. Glad its not the phone.

I'm actually having the same thing... keeps switching to 3G randomly, after a reboot it'll go to 4G LTE and usually stay, but often if I make a call, or do something it'll switch back to 3G for some time, then maybe go back to 4G... stock KK rooted here too
Did the SIM card fix it for you permanently? I may try getting a new one if so.
I'll second this. Had the same problem. New sim card and bam, fixed. For some reason I think going to international ROMs (cloudy and optimus) caused this.... The 3g roaming thing.. which is a shame because their ROMs are freaking awesome.

Yeah I went to my local mom & pop Verizon store and the idiot behind the counter said my old LTE sim card wasn't NFC ( Near Field Communications) complaint. Why is he an idiot that's another story. But I don't know how NFC has anything to do with the sim card. Anyway I bought a new one because they weren't a official Verizon store, supposedly the official store will give you a new sim card. But now the phone works like it is suppose too.
